SPRAYTEK99 ®

QSOLAR leads the solar panel technology with innovative ideas and a wide range of products designed to meet the needs of any solar

power application

Most solar PV manufacturers are using a similar manufacturing technique which involves the encapsulation of solar cells between 2 EVA

sheets and laminating the resulting encapsulation between glass and tedlar. This involves an expensive flat bed laminator, a process

which is both time consuming and which requires a lot of energy thus adding a significant cost in the manufacturing process.

Other manufacturers are pursuing research on different materials to reduce the cost but with significantly lower conversion efficiency

at present.

At QSOLAR we took a different approach in improving an already established technology using the crystalline silicon cells; but instead of using an expensive laminator to seal the cells, we have adopted a spraying technique we called SPRAYTEK99 ® using a highly protective insulator plastic compound which forms an impenetrable film around the cell protecting it from the weather under any conditions.

This process is 35% faster than any manufacturing technology available in the market, does not need a laminator, uses much less power, doesn't need EVA anymore, doesn't need TPT anymore and doesn't need expensive glass anymore...the glass is now replaced by an ultra light composite matérial which is stronger than glass and 50% lighter resulting in an overall reduction of the photovoltaic manufacturing cost.

The major bottleneck in any automatic PV manufacturing line is the lamination process; this is why production lines use multiple laminators to achieve the required throughput. The reason is the time it takes to cut and position the EVA sheets for encapsulation of the solar cells as well as the actual lamination process. This leads to significant increase of the total investment and operational cost.

A laminator due to the use of pressure and heating processes needs a significant amount of energy; a typical large laminator needs 175 KW to operate. For a 24 hour shift the required energy is 175 x 24 = 4200 KWH a day or 1,533,000 KWH a year with a cost of $0.1 per KWH this becomes $153,000 cost of electricity per laminator per year; this and the time required for lamination adds a significant amount of cost to the solar module.

By eliminating the laminator and using a spraying process the time required for the manufacture of solar modules as well as the energy required together with the initial investment is drastically reduced. This increase in throughput and cost reduction results in very significantly lower production cost and therefore a lower PV module cost.

Last but not least, our process SPRAYTEK99 ® does not generate any harmful emissions during operation and production...for the greenest of the green ! …
